Abstract A chemical modification of cotton fabrics by 2-diethylaminoethyl chloride (DEAE-Cl) was achieved, and the resulted demonstrated salt-free dyeing properties with anionic dyes. Nucleophilic property hydroxyl groups in cellulose enhanced under alkaline conditions could react DEAE-Cl, a possessing both nucleophilic electrophilic sites. The monolayered DEAE-grafted further DEAE-Cl to form m...
